Classify the quadrilateral Then, find x and y.

Square

x = 2

y = 1

Step-by-step explanation:

Measures of all ll sides of a square are equal.

Therefore,

5x - 4 = 3x

5x - 3x = 4

2x = 4

x = 4/2

x = 2

5y + 1 = 2y + 4

5y - 2y = 4 - 1

3y = 3

y = 3/3

y = 1

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
